Introduction Two basic types of Poultry Enterprises:

►Broiller – Used mainly for meat.

►Layer – Used mainly for egg production.

Poultry Production in NC

– Broilers –



Broiler Production

• Broilers are grown on the floor of large “Broiler Houses.” Each house can hold over 100,000 birds.

Broiler Production



Broiler Production• Broilers will reach market

weight and maturity in about 9 weeks.

• They will be between 3 and 5 lbs in weight.

• They will be used for whole fryers or cut into parts or specialty cuts for the grocery store.



Broiler Production

• Almost 99% of all Broilers grown in the US are grown on Vertical Integration systems.

• Vertical Integration is when two or more steps of production, marketing or processing are linked.



Broiler Production

• Vertical Integration is like contract growing:• The grower signs a contract in which:• The grower provides the house, and is

guaranteed a price for each bird produced.• The producer provides everything else to the

grower.

– Layers –



Layers

• Layers are kept in “layer cages” in large open barns.



Layers

• The cages are often stacked on top of each other to increase the number of layers in an area



Layers

• The cages are tilted so that eggs will collect at the front of the cage and then can be transported to a collection area



• Layers begin producing eggs at 21 weeks of age, then they will produce an average of an egg a day for the first year.

• They next go through a molting period for approximately 3 months in which they will stop producing eggs and produce new feathers.

• Artificial light is used to increase the laying ability of the birds



• The collected eggs are unfertilized and must be refrigerated within 5 hours to ensure freshness.

• The eggs are weighed, inspected and candled to determine quality.



Quality Factors

• Confirmations – ideal is normal breastbone, back, legs and wings

• Fleshing – well fleshed or muscled is ideal • Fat covering – well covered is ideal



Quality Factors

• Exposed flesh – none is ideal, to grade A – breast and legs cannot have more than

• 1/4" exposed flesh (under 6 lb. carcass) from cuts, tears. Other parts such as back and wings can have from 1” to 3” depending on weight of carcass with larger carcasses able to have more and still be grade A



Quality Factors

• Discolorations – from bruises not allowed on breast and legs of grade A, some from other causes allowed.

• Disjointed and broken bones – no broken and one disjointed allowed for grade A.

• Missing parts – wing tips and tail can be missing on grade A

• Freezing defects – slight ones allowed for grade A.



USDA Ready-to Cook Poultry Grade

• A, B, C, No Grade – from best to worst

• Ready-to cook means the head, feet feathers, blood and viscera (soft internal parts) have been removed.

• USDA Grades indicate quality, NOT sanitation
